Calculation of Total Pages in the Manuscript

To calculate the total number of pages in the manuscript, we can use the information provided.

The operator typed 28% of the pages on the first day and 20% of the pages on the second day. After these two days, the operator had 39 pages left to type.

Let's denote the total number of pages in the manuscript as "x".

On the first day, the operator typed 28% of x, which is 0.28x pages. On the second day, the operator typed 20% of x, which is 0.20x pages.

After these two days, the operator had 39 pages left to type. Therefore, we can set up the following equation:

x - (0.28x + 0.20x) = 39

Simplifying the equation:

x - 0.48x = 39

0.52x = 39

Dividing both sides of the equation by 0.52:

x = 39 / 0.52

Calculating the value:

x ≈ 75

Therefore, the total number of pages in the manuscript is approximately 75 pages.
